Hi everyone. I'm very new into self learning programming. Presently I'm trying to develop a simple basic Robot that would only Place a Market Order every seconds and it will cancel the Order every followed seconds. Using the following library: https://docs.b2bx.exchange/en/_docs/api-reference.html#private-api It would place Trade Order at a ( Price = ex.com api * Binance api Aggregate Trades Price) I have already wrote the api to call for xe.com exchange rate with php <?php $auth = base64_encode("username:password"); $context = stream_context_create([ "http" => [ "header" => "Authorization: Basic $auth" ] ]); $homepage = file_get_contents("https://xecdapi.xe.com/v1/convert_from?to=NGN&amount=1.195", false, $context ); $json = json_decode($homepage, TRUE); foreach ($json as $k=>$to){ echo $k; // etc }; ?> And also for the Binance Aggregate Price in JavaScript <script> var burl = "https://api3.binance.com"; var query = '/api/v3/aggTrades'; query += '?symbol=BTCUSDT'; var url = burl + query; var ourRequest = new XMLHttpRequest(); ourRequest.open('GET',url,true); ourRequest.onload = function(){ console.log(ourRequest.responseText); } ourRequest.send(); </script> My problem is how to handle these two api responds and also the functions to use them to place a trade and cancel it. Please help me out. Thanks in advance on any help.
